try a pair of levis 510s. they fit perfectly, they were really inexpensive and i didnt have to get the ends tailored. ive never been happier with a pair of jeans! good luck!
definitely cuff your jeans. i always cuff mine. its great way to show some ankle or a cool pair of socks you have on. heres a great guide to show you how. good luck!
same way you would roll a shirt sleeve. thanks for the kind words! good luck!
look for styles you like and then find those items at local thrift stores and department stores like marshalls, sears and kohls. once you have more money maybe invest in a few nicer pieces at a store like zara, uniqlo or jcrew. good luck!
